ANTISLIPPENG- DEVICE.

Application filed November 19, 19244 Serial No. 750,761.

To @ZZ whom it may concern.'

Be it known that I, Jol-1N GEMZA, a citi zen ol Poland, and resident ofMiry Broeck, Danbury, in the county of Fairfield and State ofConnecticut, have invented certain new and use'ful Antislipping Devices,of which the following is a speciication.

This invention relates to improvements in antislipping devices,particularly ice-creepn 1G ers, designed for attachment to the heels otboots or shoes, and has for its principal object to provide a noveldevice which can be readily attached to and detached from the heel ot a'boot or shoe.

Another object oit the invention is the provision of a Creeper of thischaracter which can quickly be adjusted to any size of heel and lockedin its adjusted positions.

A further object of the invention is the provision of a Creeper for theheels of footwear of simple and inexpensive construction provided withmeans for securely engaging` the material of the shoe at the heelthereof in front as well as in rear thereof.

These and other objects and advantages of my invention will become morefully known as the description thereof proceeds, and will then bespecilically pointed out in the appended claims.

In the accompanying drawing, forming a material part ot t is disclosure:

Figure 1 is a side view of a Creeper con structed according` to theinvention, attached to a heel.

Figure 2 is a bottom plan view of the same looking in the direction ofthe arrows 2-2 of Figure 1.

Figure 3 is a similar view to Figure 1 with the creeper in positionready for attachment to a heel.

Figure 11 is a cross-section on line 1-4 ot' Figure 1.

Figure 5 is an end view looking in the di.- rection of arrows 5-5 ofFigure 1.

The Creeper comprises a top or heel engaging plate having at one endupstanding` heel engaging` fingers 11 or the like, equipped at theirupper ends with prongs 12 and intermediate their ends with other prongs1? 50 adapted to be embedded into the material of the heel 14 of a shoeor boot. At its lower :tace near the end equipped with the spacedkfingers 11, the plate 10 carries depending ground engaging prongs 15,one on each side,

and intermediate its ends the plate 10 carries similar depending groundengaging` prongs 16, one on each side.

A sliding plate 17 provided with longitudinal slots 18 on each side ofits longitudinal central is slidably engaging the lower face of plate 10and the prongs 16 of plate 10 extend through the slots 18 for guidingthe plate 17 during its sliding motion. At its free end the slidingplate 17 carries upright prongs 19, adapted to engage the material ofthe heel and located to both sides of a marginal recess 20 in the endor' plate 17. At the inner edge of the recess the plate 17 is equippedwith two depending ground engaging prongs 21.

Pintles 22 at the end of a yoke 23 engage pivotally the prongs 1G, andthe connecting bar at the opposite end of the yoke has an angular armthrough which extends a shank 25 carrying at its outer end an operatingknob 2G or the like, and at its inner end a locking plate 27 adapted tobe passed in one of its positions through the space between lingers 11and in its turned or locking` position engage the inner 'faces of theseiin-v gers in the manner illustrated in Figure The longitudinal branchesor the yoke 23 carry on their inner edges langes angularly disposed tothe said branches and each provided with a plurality oit perforations29' adapted to be engaged by the hooked ends ot a spring 30 havingsubstantial ltl-shape. rlhe connecting bar or' the U-spring branches arerotatably arranged in a socket 31 attached to the lower face of theslide plate 17. Between the branches of the yoke 23, a bar 32 isintegrally made with the connecting bar oit' the branches ot' the yoke,and its other end is attached to a` median bar 33 of the stationaryplate 10 which has its material cut out to both sides of this bar 33, asat 34 and 35.

rlhe operation of the device is evident from the above description. Ifthe device is to be attached to a heel, the yoke is turned around thepivot points 22 to assume the position illustrated in Figure 2, whilethe ends of spring 30 are introduced in the respective holes of theflanges 28 in order to adjust and lock the parts in their respectivepositions litting the particular size and heel. lVhen then the yoke isswung about the pivot points 22 and the locking plate is passed throughthe space between fingers 11, and turned behind the same by means ofknob 26 so as to engage the rear faces of the fingers in the mannerillustrated in Figure the device will be firmly secured to the heel asthe prongs l2, 13 and 19 will be rmly embedded into the material of theheel.

It is to be understood that changes may y be made in the generalarrangement and in the construction of the minor details of my inventionwithout departing from the scope and spirit of theV same as defined inthe appended claims. y

Haif'ing thus described my invention, what I claim as new and desire toprotect by Letters Patent is:

l. In a device of the class described, the combination of a stationaryand a movable plate, a yoke on said movable plate having` the lower endsof its branches attached to the stationary plate, a median bar on saidyoke attached at its lower end to said stationary plate, perforatedflanges on the f branch bars of said yoke angularly disposed thereto,and a U-spring adapted to engage with its hook-shaped free ends into theperforations of said flanges, and a socket on said movable plate inwhich the connecting har of the J-spring is turnably located.

2. In an antislipping device of the class described for the heels offoot wear, the coinbination of a stationary plate, a median bar on saidplate and openings in said plate to both sides of said median bar, witha sliding' plate adapted to slide overv the lower face of saidstationary plate, ground engaging prongs on said stationary plateintermediate the ends thereof, a yoke havingy pintles at its lower endspivotally engaging said prongs, a median bar on said yoke having its-free end secured to the me dian bar of said stationary plate, twoupstanding spaced fingers at one end of said stationary plate, a lockingplate on said yoke adapted to be introduced through the space betweensaid fingers behind the same and to be turned for locking the parts intheir adjusted position, and means for allowing an adjustment andlocking of the relati ve positions of both plates for any size of heel.
